From d08619bfe1a3cbc593bdaae5a5bd393e1d33f150 Mon Sep 17 00:00:00 2001 From: Quincey Koziol Date: Sat, 19 Jul 2008 21:32:47 -0500 Subject: [svn-r15388] Description: Convert object header cache client to use the new metadata journaling cache, which included adding a new client for handling continuation chunks. Added "real" protect calls around modifying chunks in object headers. Switched a few more metadata cache library API routines to drop the file pointer, when it is not needed (pinning/unpinning entries, etc.) Fixed bug in journaling cache handling of 'image_len' callbacks and also changed cache to retry deserializing entries when the entry's size is larger than the speculative size initially tried. Retrying for 'image_len' callbacks has problems with the 'multi' VFD, so the h5dump and FORTRAN 'multi' tests are commented out, until the changes to the 'multi' VFD from the file free space branch are brought back into the trunk. Currently, the 'h5recover' tool has a bug which requires it to be run twice before replaying the journal "sticks". However, this is from an earlier checkin, since the code in the branch already has this behavior... :-( Tested on: FreeBSD/32 6.2 (duty) in debug mode FreeBSD/64 6.2 (liberty) w/C++ & FORTRAN, in debug mode Linux/32 2.6 (kagiso) w/PGI compilers, w/C++ & FORTRAN, w/threadsafe, in debug mode Linux/64-amd64 2.6 (smirom) w/default API=1.6.x, w/C++ & FORTRAN, in production mode Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN, in production mode Solaris/32 2.10 (linew) w/deprecated symbols disabled, w/C++ & FORTRAN, w/szip filter, in production mode Mac OS X/32 10.5.4 (amazon) in debug mode Linux/64-ia64 2.4 (tg-login3) w/parallel, w/FORTRAN, in production mode --- MANIFEST | 1 + fortran/test/fortranlib_test.f90 | 7 +- src/H5A.c | 2 +- src/H5AC2.c | 139 ++-- src/H5AC2pkg.h | 10 +- src/H5AC2private.h | 24 +- src/H5Adeprec.c | 2 +- src/H5B2cache.c | 54 +- src/H5B2pkg.h | 6 +- src/H5Bcache.c | 9 +- src/H5C2.c | 196 ++++-- src/H5C2journal.c | 33 +- src/H5C2pkg.h | 2 +- src/H5C2private.h | 20 +- src/H5Dint.c | 30 +- src/H5Dio.c | 3 + src/H5FS.c | 4 +- src/H5FScache.c | 31 +- src/H5FSsection.c | 26 +- src/H5Gnode.c | 41 +- src/H5Gobj.c | 20 +- src/H5O.c | 595 +++++++++++++--- src/H5Oalloc.c | 367 +++++++--- src/H5Oattribute.c | 180 +++-- src/H5Ocache.c | 1446 +++++++++++++++++++++----------------- src/H5Ochunk.c | 355 ++++++++++ src/H5Ocont.c | 6 +- src/H5Ocopy.c | 27 +- src/H5Odbg.c | 22 +- src/H5Ofill.c | 1 + src/H5Omdj_msg.c | 1 - src/H5Omessage.c | 127 ++-- src/H5Opkg.h | 82 ++- src/H5Oprivate.h | 14 +- src/H5Otest.c | 77 +- src/H5SM.c | 20 +- src/H5SMpkg.h | 1 + src/Makefile.am | 2 +- src/Makefile.in | 5 +- test/cache2.c | 27 +- test/cache2_common.c | 12 +- test/cache2_journal.c | 12 +- test/ohdr.c | 30 + testpar/t_cache.c | 14 +- testpar/t_cache2.c | 25 +- testpar/t_pflush1.c | 1 - testpar/t_posix_compliant.c | 2 +- tools/h5dump/testh5dump.sh.in | 5 +- tools/h5recover/h5recover.c | 18 +- 49 files changed, 2738 insertions(+), 1396 deletions(-) create mode 100644 src/H5Ochunk.c diff --git a/MANIFEST b/MANIFEST index 424338b..6c59d98 100644 --- a/MANIFEST +++ b/MANIFEST @@ -626,6 +626,7 @@ ./src/H5Obogus.c ./src/H5Obtreek.c ./src/H5Ocache.c +./src/H5Ochunk.c ./src/H5Ocont.c ./src/H5Ocopy.c ./src/H5Odbg.c diff --git a/fortran/test/fortranlib_test.f90 b/fortran/test/fortranlib_test.f90 index 2bc2ab7..6141f37 100644 --- a/fortran/test/fortranlib_test.f90 +++ b/fortran/test/fortranlib_test.f90 @@ -154,8 +154,11 @@ PROGRAM fortranlibtest ret_total_error = 0 cleanup = .FALSE. - CALL multi_file_test(cleanup, ret_total_error) - CALL write_test_status(ret_total_error, ' Multi file driver test', total_error) +!
